Background: Preclinical studies suggest that for complete midsubstance anterior cruciate ligament (ACL) injuries, a suture repair of the ACL augmented with a protein implant placed in the gap between the torn ends (bridge-enhanced ACL repair [BEAR]) may be a viable alternative to ACL reconstruction (ACLR). Between 2006-2012, doctors and researchers with Rhode Island Hospital, Brown University, and Boston Childrens, collaborated for a series of preclinical studies that were performed to optimize the implant, to demonstrate the safety of its use in the body, and to show that it stimulated the ACL to heal.
